4x4 Proyect 2.65 PreRunner Suspension Kit

This is one of the most impressive suspension systems we’ve ever run on any platform, and for the INEOS Grenadier, we do not think it gets better than this.

The 4x4 Proyect 2.65 PreRunner Suspension Kit is a serious high-performance shock system designed specifically for the Grenadier. It brings race-developed suspension technology into a vehicle that already starts with an incredibly capable chassis, then makes it dramatically better everywhere: on the street, on the highway, across washboards, through high-speed desert terrain, and on technical trails where control matters as much as clearance.

We ran this system on our own APEX Grenadier Moab build, and it completely changed the character of the truck. The Grenadier feels more planted, more controlled, more composed, and far more confident without becoming harsh or annoying to drive every day. That is the real magic here. A lot of suspension systems improve trail performance by compromising road manners. This one improves both.

The 4x4 Proyect PreRunner system is built around large 2.65-inch shocks with self-adjusting digressive valving designed to adapt to changing terrain without requiring constant manual adjustment. In practical terms, that means the truck can feel stable and predictable at speed, absorb rough terrain more effectively, and maintain the kind of ride control that makes the Grenadier feel significantly more refined than stock.

This is not the suspension you buy because it looks good on a spec sheet. This is the suspension you buy when you want the Grenadier to drive the way it always should have. More control. More confidence. More speed when the terrain opens up. More composure when the trail gets ugly. More comfort on the drive home.

For clients building a Grenadier that needs to work in the real world, this is the top of the food chain.
